A method of reversed-phase liquid chromatography coupled with mass spectrometry (LC-MS) in combination with a stable isotope dilution assay was used to quantify acrylamide in potato chips. This in-house procedure was evaluated for precision, and accuracy. LC-MS revealed as a cost-effective and robust technique for acrylamide analysis in potato chips. Acrylamide formation was studied during deep...

Oil supplementation in dairy cattle diets is used to modulate milk fat composition, as well as the expression of mammary lipogenic genes, whose regulation remains unclear. MiRNAs are small non-coding RNA considered as crucial regulators of gene expression, offering clues to explain the mechanism underlying gene nutriregulation. The present study was designed to identify miRNAs whose expression ...

BACKGROUND This study was conducted to evaluate the effects of consuming thermally oxidized oil supplemented with pectin on liver glutathione peroxidase activity, serum malondialdehyde and lipid profiles in male Sprague-Dawley rats. METHODS Fifty growing male Sprague-Dawley rats were randomly divided into different groups. The diets differed only in their fat and pectin content. The diets had...

Antioxidant activity of skin from runner peanut was performed on sunflower refined oil. The skin was obtained from industrial blanching process. The oil was oxidized at 60oC. The methanolic extracts show antioxidant activity in relation to the oil (without additives). However these extracts do not reach the activity level from BHT.

In the present study, the aflatoxin B1 contamination at various stages of oil refining and in refined oil were carried out. This was subsequently compared with commercial vegetable oil samples. Among the 23 different sunflower oil samples were tested, 10 of them showed positive results to AFB1 and the remaining 13 showed negative results to AFB1. All the refined oil samples were free from AFB1 ...

OBJECTIVE: We investigated whether the intake of virgin olive oil or sunflower oil and performance of physical exercise (at different states) affect plasma levels of triacylglycerols, total cholesterol, and fatty acid profile in rats. METHODS: The study was carried out with six groups of male rats subjected for 8 wk to a diet based on virgin olive oil (three groups) or sunflower oil (three grou...

Aflatoxin, a mycotoxin found commonly in maize and peanuts worldwide, is associated with liver cancer, acute toxicosis, and growth impairment in humans and animals. In Tanzania, sunflower seeds are a source of snacks, cooking oil, and animal feed. These seeds are a potential source of aflatoxin contamination. However, reports on aflatoxin contamination in sunflower seeds and cakes are scarce. T...

essential oils (eos) extracted from aerial parts of aster indamellus grierson, calamintha umbrosa benth. and erigeron annuus (l.) pres.were analyzed by gc, gc/ms. the major acetylenic constituent (cis-lachnophyllum ester) of e. annuus was isolated and characterized by 1h and 13c-nmr spectra. their toxicity and repellent effect against lipaphiserysimi was tested. oils of e. annuus and c. umbrosa...

In vitro transcorneal permeation of diclofenac from oil drops was studied using freshly excised goat cornea. The maximum apparent corneal permeability coefficient (Papp) was obtained with 0.2% (w/v) diclofenac drops in sesame oil followed by safflower oil, while formulation in castor oil provided minimal Papp. The addition of benzyl alcohol, a preservative, in oil drops, increased the Papp valu...
